door is opened with the ignition switched on.
WARNING
● Never run the engine in confined spaces, as the exhaust gases are
poisonous.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could suddenly lock, making it impossible to
steer the vehicle: risk of accident!
● Always take the key with you when you leave the vehicle. This is par-
ticularly important if there are children in the vehicle, as they might oth-
erwise be able to start the engine or use power-operated equipment (e.g.
the electric windows), which could cause injuries.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This will help avoid unnecessary
exhaust emissions.
Note
● If it is difficult to turn the ignition key to the position 1, turn the steer-
ing wheel to both sides to release the steering lock.
● When starting from cold, the engine may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve lifters. This is
quite normal, and no cause for concern.
● If the vehicle battery is disconnected and reconnected, the key must re-
main in the position 1
for around 5 seconds before starting up.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). Next, the selector lever is locked. 

Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fastened.
● The bonnet must be closed.
● The vehicle must have travelled at more than 4 km/h (2 mph) since the
last stop.
● The vehicle cannot be towing a trailer.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.
● To avoid injury, make sure that the Start-Stop system is switched off
when working in the engine compartment ⇒ page 152.
CAUTION
The Start-Stop system must always be switched off when driving through
flooded areas ⇒ page 152. Stop/Start the engine

Additional information related to the automatic gearbox
The engine stops when the selector lever is in the positions P, D, N and S, in
addition to when in manual mode. With the selector lever in position P, the
engine will also remain switched off when you take your foot off the brake
pedal. In order to start the engine up again the accelerator must be press-
ed, or another gear engaged or the brake released.
If the selector lever is placed in position R during the stopping phase, the
engine will start up again.
Change from position D to P to prevent the engine from accidentally starting
when changing and passing by position R. 

Automatic gearbox/DSG automatic gearbox*
Introduction
Your vehicle is equipped with an electronically controlled manual gearbox.
Torque between the engine and the gearbox is transmitted via two inde-
pendent clutches. They replace the torque converter found on conventional
automatic gearboxes and allow for smooth, uninterrupted acceleration of
the vehicle.
The tiptronic system allows the driver to change gears manually if desired
⇒ page 159, Changing gears in tiptronic mode*. 
Selector lever positions
The selector lever position engaged is highlighted on the display in the in-
strument cluster. With the selector lever in the manual gearbox positions G,
D, E and S, the engaged gear is also indicated on the display.
P – Parking lock
When the selector lever is in this position, the driven wheels are locked me-
chanically. The parking lock must be engaged only when the vehicle is sta-
tionary ⇒ 
.
The interlock button (the button on the selector lever handle) must be
pressed in and simultaneously the brake pedal must be depressed before
moving the selector lever either in or out of position P.
R – Reverse gear
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling ⇒ 
.
To move the selector lever to position R, the interlock button must be press-
ed in and at the same time the brake pedal must be depressed. The reverse lights come on when the selector lever is in the R position with the ignition
on.
N – Neutral (idling)
With the selector lever in this position, the gear is in neutral.
D/S – Permanent drive (forward) position
The selector lever in the D/S position enables the gears to be controlled in
normal mode (D) or Sport (S). To select Sport mode (S), move the selector
lever backwards. Moving the lever again will select normal mode (D). The
selected driving mode is shown on the instrument panel display.
In normal mode
(D), the gearbox automatically selects the best gear ratio.
This depends on the engine load, the road speed and the dynamic gear
control programme (DCP).
Sport mode (S) must be selected for a sporty driving style. This setting
makes use of the engine's maximum power output. When accelerating the
gear shifts will be noticeable.
The brake pedal must be pressed when moving the selector lever from D/S
to N if the vehicle is stationary or at speeds below 5 km/h (3 mph) ⇒ 
.
Under certain circumstances (e.g. when driving in mountains) it can be ad-
vantageous to switch temporarily to tiptronic mode ⇒ page 159, in order to
manually select gear ratios to suit the driving conditions.
WARNING
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) resulting in the risk
of an accident.
● Never move the selector lever to R or P when driving. Failure to do so
could result in an accident. 

Changing gear manually with the selector lever
It is possible to change to tiptronic mode, both when the vehicle is
stopped and while driving. –
To switch to tiptronic mode, move the selector lever from posi-
tion D/S to the right. As soon as the change is made, the selec-
tor lever will be shown in the position G (i.e. G4 means that 4th
gear is engaged) on the instrument panel display.
– Move the selector lever forwards +
to select a higher gear
⇒ Fig. 91.
– Move the selector lever backwards -
to select a lower gear.
Changing gear manually with the gearshift paddles*
The gearshift paddles can be used when the selector lever is in the
position D/S or G.
– Press the gearshift paddle +
to select a higher gear
⇒ Fig. 92.
– Press the gearshift paddle -
to select a lower gear.
– With the selector lever in position D/S, if no paddle is operated
during a short period of time, the gearbox control system
switches back to automatic mode. To switch to permanent man-
ual gear change using the gearshift paddles, move the selector
lever from position D/S to the right.
When accelerating, the gearbox automatically shifts up into the next gear
shortly before the maximum engine speed is reached.
If you select a lower gear, the automatic gearbox will not shift down until
there is no risk of overrevving the engine.
When the kick-down feature is used, the gearbox shifts down to a lower
gear, depending on road speed and engine speed. 

Lane Assist system* Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
The intelligent technology in the Lane Assist system cannot change the
limits imposed by the laws of physics and by the very nature of the sys-
tem. Careless or uncontrolled use of the Lane Assist system may cause
accidents and injury. The system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● Always keep your hands on the steering wheel so it can be turned at
any time.
● The Lane Assist system does not detect all road markings. The road
surfaces, road structures or objects in poor condition can be incorrectly
detected as road markings under certain circumstances by the Lane As-
sist system. In such situations, switch the Lane Assist system off imme-
diately.
● Please observe the indications on the instrument panel and act as is
necessary.
● Always pay attention to the vehicle's surroundings.
● When the area of vision of the camera becomes dirty, covered or is
damaged, the Lane Assist system function can be affected.
CAUTION
In order to avoid influencing the operation of the system, the following
points must be taken into account:
● Regularly clean the area of vision of the camera and keep it in a clean
state, without snow or ice.
● Do not cover the area of vision of the camera.
● Check that the area of vision of the windscreen camera is not damaged. 

● Stop the vehicle safely as soon as possible.
Note
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle. Operating mode
Fig. 99 In the wind-
screen: Field of vision of
the Lane Assist system
camera
Using the camera located in the windscreen, the Lane Assist system detects
the possible lines dividing the lanes. When the vehicle involuntarily ap-
proaches a dividing line it has detected, the system notifies the driver with
a corrective steering movement . The corrective steering movement can be
overruled at any moment.
No warning is produced with the turn signals activated, given that the Lane
Assist system understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in the steering wheel and require
the driver to take active control of driving:
● When the limits of the very nature of the system are reached.
● When the maximum rotational torque during the corrective steering
movement is not enough to keep the vehicle inside the lane.
● When no lane is detected during the corrective steering movement. 

Tyre monitoring systems Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Caring for and cleaning the vehicle exterior ⇒ page 198
● Wheels and tyres ⇒ page 223
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre
pressure losses, to tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. Tyre pressure that is too low could cause overheat-
ing, resulting in tread detachment or even burst tyres.
● Tyre pressure should be that indicated on the label when the tyres are
cold at all times ⇒ page 266.
● Regularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
● Regularly check your tyres for damage and wear.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 

text message can be seen on
the instrument panel display. Stop the vehicle! Reduce
speed immediately! Stop the
vehicle safely as soon as
possible. Avoid sudden ma-
noeuvres and braking! Check
all tyres and pressures. Re-
place any damaged tyres.

about one minute and then
lights up permanently.
If the tyre pressure is correct,
switch the ignition off and on
again. If the control lamp re-
mains lit up, the tyre monitor-
ing indicator can be calibra-
ted. Have the system re-
viewed by a specialised
workshop. 

Tyre monitoring indicator
Fig. 102 Glove compart-
ment: tyre control switch
The tyre monitor indicator compares wheel revolutions and, with this infor-
mation, the tread of each wheel using the ABS sensors. If the tread of one or
more wheels is changed, the tyre monitoring indicator will indicate as such
on the instrument panel.
Wheel tread change
The wheel tread changes when:
● Tyre pressure is manually changed
● Tyre pressure is insufficient
● Tyre structure is damaged
● The vehicle is unbalanced because of a load
● The wheels on an axle are subject to a heavier load (e.g. when towing a
heavy load)
● The vehicle is fitted with snow chains
● The temporary spare wheel is fitted
● The wheel on one axle is changed There may be a delay in the reaction of the tyre monitoring indicator
 or it
may not indicate anything under certain circumstances (e.g. sporty driving,
snow-covered or unpaved roads, or when driving with snow chains).
Calibrating the tyre monitoring indicator
After changing the tyre pressure or replacing one or more wheels, the tyre
monitoring indicator must be recalibrated. Do the same, for example, when
the front and rear wheels are swapped.
● Switch the ignition on.
● Store the new tyre pressure in the Easy Connect system with the button

and the function button Setup ⇒ page 80 or using the switch located in
the glove compartment* ⇒ Fig. 102.
When driving, the system self-calibrates the tyre pressure provided by the
driver and the wheels fitted. After a long journey with varied speeds the pro-
grammed values are collected and monitored.
With the wheels under very heavy loads, the tyre pressure must be in-
creased to the total recommended tyre pressure before the calibration
⇒ page 266.
Note
● The tyre monitoring indicator does not function when there is a fault in
the ESC or ABS ⇒ page 183.
● An erroneous indication may be given when snow chains are in use be-
cause the chains increase the tread of the wheel. 
